Thread: Exception issue

Okay. Wow.

I'm not reading through all of that code, and I'm sure this has been said, but it could stand repeating: start with a clean source file adding only a little back, compiling each addition, until you find where your bug lives.

Or, you know, post the example as you've been asked.

I asked for "how to use std instead od declaring it "using namespace std" and also whether std::setw is correct or not as its not working for me ...even if you write std:: and see the drop down menu provided by compiler environment you didn't see such a STUFF........
WHAT you Suggested is am doing already

You've done that before, at least within your post, e.g., use std::setw instead of setw. Still, it would be better to figure out why the name is ambiguous in the first place rather than blindly fully qualifying the name.

How does it not work?

Not likely:

Maybe your "compiler environment" is broken or its internal state was not updated to include the symbol somehow. Maybe you just didn't see the "STUFF". Maybe when removing the unnecessary headers, you accidentally removed <iomanip> (or rather did not move it to the source file). Maybe, maybe, maybe.

What is the current code, particularly the line that contains the setw call? What's the error message? What's the incorrect output? As long as you don't say that, just saying "its not working for me" is not very useful. I can only tell you: go and fix it.

Put it another way. Compile and run this program:

Code:

#include <iostream>
#include <iomanip>

int main()
{
    using namespace std;
    int x = 123;
    cout << setfill('0') << setw(4) << x << endl;
}

What error messages do you get? If it compiles, what is the output?
